Abstract: A paper following on from the paper “Between the idea and reality” (Nursing Praxis in New Zealand 1(2), 17-29) proposing the focus for the discipline of nursing – practice and research – is diagnosis. For nursing practice, diagnosis is a practice that collapses “The Nursing Process”; for research to develop nursing practice, diagnosis is one continuous relational process that merges and makes the separate tasks od assessment, intervention and evaluation redundant.
